Savannah River Annotated Bibliography: January 2003 (3) AQUATIC BIOTA (compiled and annotated by Will Duncan, Tavis McLean, Mary Freeman, Cecil Jennings The annotated bibliography below is divided into ten sections: Atlantic and shortnose sturgeon, Shad and Herring, American eel, striped bass, robust redhorse, habitat, flow and other fish, mussels, floodplain fish, estuaries and general information sources. They are ordered by the authors last name, not relevance. Atlantic and Shortnose Sturgeon Buckley, J., and B. Kynard. 1985. Habitat use and behavior of prespawning and spawning shortnose sturgeon, Acipenser brevirostrum, in the Connecticut River. Pages 111-117 in F.P. Binkowski and S.I. Doroshov, eds. North American sturgeons: biology and aquaculture potential. Developments in Environmental Biology of Fishes 6. Dr. W. Junk bv Publishers, Dordrecht, Netherlands. 163 pp. Collins, M.R., S.G. Rogers, T.I.J. Smith, and M.L. Moser. 2000a. Primary factors affecting sturgeon populations in the southeastern United States: fishing mortality and degradation of essential habitats. Bulletin of Marine Science. 66, 917-928. Reviews sources of mortality and habitat degradation for anadromous (Atlantic) and nearly anadromous (shortnose) sturgeon. Some life stages are restricted to or concentrated in estuaries and deterioration of dissolved oxygen levels in these areas has degraded these habitats. Protecting these areas from human induced DO drops and creating habitat preserves to eliminate bycatch may benefit these species. Although the spawning habitat for the Atlantic sturgeon is unknown, shortnose appear to spawn at limestone outcrops or deep, scoured channels with hard substrate. Nursery habitat for both species appears to be the interface between fresh and brackish water. For the Savannah River, Collins et al. make three management recommendations: halt degradation of nursery habitat (salinity and DO), establish riverine reserve to the first dam at rkm 300, and maintain adequate flow from dam during spawning season. Collins, M.R., T.I.J. Smith, W.C. Post, and O. Pashuk. 2000b. Habitat utilization and biological characteristics of adult Atlantic sturgeon in two South Carolina rivers. Transactions of the American Fisheries Society 129, 982-988. Radio telemetry studies revealed seasonal movement patterns of the Atlantic sturgeon in nearby South Carolina rivers. All fish were between the ages of 7 and 20 years old, but fewer females were found in the rivers. Additionally, females were older (aged 15-20). All fish moved out to sea between October and November. Some data suggest upstream spawning runs in October. Nearly half returned in March. Fall and spring spawning was documented. Summer habitats included upper and lower estuaries, tidal freshwater, river, and perhaps the ocean. This study suggest little differentiation between rivers in the ACE basin. Some WQ data related to habitat use is available. Collins, M.R., W.C. Post, D.C. Russ, and T.I.J. Smith. 2002. Habitat use and movements of juvenile shortnose sturgeon in the Savannah River, Georgia- South Carolina. Transactions of the American Fisheries Society. 131, 975-979. 37
